Wastegate Lines

Ok i have searched around the site and internet and am even more confused from when i first started. I am tying to hook up my Greddy profec 2 boost controller. I have a Tial external wastegate and am confused on where the vac lines go. The one from the boost controll valve goes to the side or top of the wastegate? some setups have two lines coming off of the wastegate some have one. I am lost on which way is the correct way for this setup and the RX8. Any help on how this should be routed would be great. Looking to get this done so i can get some more work done. Thanks guys

Your Google-fu is weak.

Side/bottom port is for compressor outlet pressure, direct.

Top port is to add pressure to boost over the rated valve spring pressure, from your boost control, which also gets it's signal line from the compressor outlet.
